To all 107mm it may concern:

Be it known that I, J oi-rN L. ZANDER, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Pencils or StylusHolders for Recording Instruments; and 1 do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tocharacters of reference me ked thereon, which form a part of thisspecification.

This invention relates, generally, to improvements in pencil or stylusholders for recording instruments of the various kinds; and, the presentinvention has reference, more particularly, to a novel construction ofpencil or stylus-holder which comprises a spring-actuated pencil orstylus and a simply constructed and novel means for positively andresiliently retaining the pencil or stylus in its marking position uponthe one end-portion of the holder.

The present invention has for its principal object to provide a noveland a simply constructed pencil or stylus holder for recordinginstruments which is of such a construction that. a short piece of thelead of an ordinary lead-pencil can be readily secured in its markingposition and has its point effectively pressed for marking upon therecord sheet or disk by means of a. simply constructed spring-device ofthe general charactor and. in the manner hereinafter more fullyspecified.

Other objects of this invention not at this time more particularlyenumerated will be clearly understood from the following detaileddescription of the present invention.

The invention consists, primarily, in the novel pencil or stylus-holderfor recording apparatus; and, the invention consists, furthermore, inthe novel arrangements and combinations of the several devices andparts, as well as in the details of the construction of the same, all ofwhich will be more fully described in the following specification andthen finally embodied in the clauses of the claim which is appended toand which forms an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is a side elevation, and Fig. 2 a top view of a pencil orstylus-holder showing one embodiment of the present invention. Fig. 3 isan end view, of the device, looking in the direction of the arrow insaid Fig. 1, said view being made on an enlarged scale; and Fig. 1- is atransverse sectional representation, on an enlarged scale, said sectionbeing taken on line 4-4 in said Fig. 1.

Similar characters of reference are employed in the said above describedviews, to indicate corresponding parts.

Referring now to the said figures of the drawings, thereference-character 1 indicates a suitable rod or stem, preferably madefrom wire, and provided at one end with a suitably fcrmed pivot-eye, as2. The opposite end-portion of the said rod or stem is provided withasuitable socket or holding element 3 for the arrangement therein of ashort pencil or stylus, as a. The said socket or holding element may beof any suitable construction, the form herein shown preferablycomprising a tubular body 5 which is provided with a rearwardlyprojecting and internally screw-threaded receiving member 6 into whichis screwed the screw-threaded end portion 7 of the said rod or stem 1.Screwed upon the said screw-threaded portion 7 is an internallyscrew-threaded sleeve 8, said sleeve being formed with a pair of lugs orcars 9 and 10, the ear 9 being provided with a screw-threaded hole 11and the ear having a hole 12 of a slightly larger diameter than the hole11, and having a smooth bore.

The reference-character 13 indicates a suitable thumb-screw, the shankof which is passed through the smooth hole 12 and screwed into thescrew-threaded hole 11. As shown in Fig. 41 of the drawings, the ears orlugs 9 and 10 may be formed with grooves or recesses, as 14, betweenwhich the shank 15 of a suitably formed spring-device is fitted, andsuitably clamped or held by the tightening of the said thumb-screw, aswill be clearly evident. The said spring device is formed with anupwardly extending portion 16 with which is connected a helical coil 17.Connected with and extending from said coil is a forwardly projectingand slightly curved presser-arm 18, the free endportion of which as willbe clearly seen from an inspection of the drawings, is fitted in therecessed end-portion 19 of the pencil or stymoved and readily replacedby a new pencil t or stylus.

I am fully aware that the spring-device may be variously secured to therod or stem 1, and that some changes may be made in the arrangements andcombinations of the parts without departing from the scope of my presentinvention as described in the foregoing specification and as defined inthe claims which are appended to the said specification. Hence, I do notlimit my inven tion to the exact arrangements of the said 1 parts as setforth 1n the said specification,

nor do I confine myself to the exact details of the construction of thesaid parts, as illustratcd in the accompanying drawings.

I claim 1. A pencil or stylus holder for recording instrumentscomprising a main stem provided at one end with a pencil orstylusaeceiving socket for the arrangement therein of a pencil orstylus, and a spring-device consisting of a sleeve arranged upon saidand thereby efiectively forces the? end-portion of the stem, a pair ofclamping ears connected with said sleeve, a thumbscrew connected withsaid ears, a shank clamped between said cars, a helical coil connectedwith said shank, and a spring-arm extending from said coil and adaptedto be brought in separable engagement with the end of the pencil orstylus.

2. A pencil or stylus holder for recording instruments comprising a mainstem formed with a screw-threaded end-portion, a tubular pencil orstylus-receiving element, and a screw-threaded receiving memberextending from said element and screwed upon the screw-threaded portionof said main stem,

said tubular element being adapted to re ceive a pencil or stylus, and aspring-device consisting of a screw -threaded sleeve screwed upon thescrew-threaded portion of said stem, a pair of clamping ears connectedwith said sleeve, a thu1nbscrew connected with said ears, a shankclamped between said cars, a helical coil connected with said shank, anda spring-arm extending from said coil and adapted to be brought inseparable engagement with the end of the pencil or stylus.

In testimony, that I claim the invention i set forth above I havehereunto set my hand this 18th day of May 1909.

JOHN L. ZANDER.
